Mood Congruence
The relationship between a patient's mood state and the content of their psychotic symptoms, particularly delusions or hallucinations.
Full Definition
Mood congruence describes whether psychotic symptoms align with the patient's prevailing mood episode. Mood-congruent psychotic features have themes consistent with the mood state, such as grandiose delusions during mania or self-deprecating delusions during depression. Mood-incongruent psychotic features have content unrelated to mood themes, such as persecutory delusions unrelated to mood or bizarre delusions. This distinction is clinically important for diagnosis, particularly in differentiating mood disorders with psychotic features from primary psychotic disorders. The presence of mood-incongruent features may suggest a more complex clinical picture or influence treatment approaches.
